json对象发布到Android应用程序中的PHP脚本(json object post to php script in android app)

 我试过这个android代码发送json对象到我的网站 
 
HttpPost httppost = new HttpPost(url);

JSONObject j = new JSONObject();
    j.put("name","name ");

        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        String format = s.format(new Date()); 
    nameValuePairs.add(new BasicNameValuePair("msg",j.toString() ));

       httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                               httpclient.execute(httppost);
 
 而这个PHP代码 
 
<?php

$msg=$_POST["msg"]; 

$filename="androidmessages.html";

file_put_contents($filename,$msg."<br />",FILE_APPEND);

$androidmessages=file_get_contents($filename);

echo $androidmessages;
?>
 
 它会告诉我{“name”：“name”}但如果我使用的话 
 
httppost.setHeader( "Content-Type", "application/json" );
 
 它没有显示任何内容。我之前没有关于json对象帖子的经验，但我认为出了问题。我想将一些用户信息发送到我的网站并在网页上显示它可以告诉我我需要改变什么才能克服这个问题问题谢谢 

I tried this android code for send json objects to my website
 
HttpPost httppost = new HttpPost(url);

JSONObject j = new JSONObject();
    j.put("name","name ");

        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        String format = s.format(new Date()); 
    nameValuePairs.add(new BasicNameValuePair("msg",j.toString() ));

       httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                               httpclient.execute(httppost);
 
And this php code
 
<?php

$msg=$_POST["msg"]; 

$filename="androidmessages.html";

file_put_contents($filename,$msg."<br />",FILE_APPEND);

$androidmessages=file_get_contents($filename);

echo $androidmessages;
?>
 
It will show me {"name":"name "} but if i use 
 
httppost.setHeader( "Content-Type", "application/json" );
